[cisco-voip] questions about sizing UC on UCS

[Ryan Ratliff (rratliff)]

Yes it would be total throughput for all the vApps combined.  The vTS and large Expressway are the only ones I can think of that would come close to pushing a Gig port to its max and that’s why the 410V has an option for a 10G adapter and the large Expressway requires a 10G adapter (and will limit you to 150 traversals if it doesn’t see one).

I'm guessing cause you can always add memory, it's not such a big deal. But it would be nice to have an alert or something.

While I understand the need to not overprovision, i.e. virtual = physical, not sure how that translates to NICs. I'm guessing total throughput required?

The tool is really only good for laying our VMs based on vCPU requirements.  It will show you the VM requirement totals for other facets, but otherwise, the IOPS, vDisk, vRAM, and vNIC are all up to you to manually validate.

I created a custom VM requiring 999GB of RAM, and placed it on a C220 M4S TRC2 a bunch if times, and the tool let me.  The tool simply does not validate RAM requirements.

I'm using this tool: http://tools.cisco.com/ucs to get an idea of a lab server that we can use to run 8 Expressway servers. Basically, a pair of C's and E's for testing and a pair of C's and E's for a pilot.

I grabbed a BE6000H (M4) [UCS 220 M4S TRC#2] [BE6H-M4-K9] and found that I could put in 8 Expressway smalls. But also mediums.

I found this strange since the total memory used is more than that which is available from the server based on the wiki.

Any comments on this?

Anyone fill a server to the max of CPU without a problem? I guess I could just add more memory if needed. They've said that does not break a server's support structure.

The "restricted" CPUs also have me wondering, but as far as I can tell, should still make a good lab server since it's usually only the size of the VM that is impacted.

Thanks, Lelio
